Interference On the Call

While the headline of this article may seem unusual to some, it’s a common problem we all deal with. On a daily basis, there are millions of electronic devices that operate in close proximity on a very narrow portion of the wireless communications spectrum that spans from 30Hz to 300GHz. Due to antenna size, power, range, cost constraints and stringent FCC regulations, most of our personal electronics crowd an even a smaller portion of that spectrum (5GHz and below). Therefore any uncontrolled electromagnetic radiation in this frequency range can interfere with the normal operation of your electronic device.

Control of electromagnetic and radio frequency interference (EMI/RFI) is a major engineering concern for all electronics manufacturers. Unfortunately, many of these problems are not known until the costly, testing stage of development. In many instances, it is discovered that a data cable or even power cord is acting as an antenna, causing unacceptable levels of interference to spill into the environment.

One of the easiest and most cost-effective solutions for this type of shielding problem is to attach a ferrite suppressor to the origination and/or termination ends of your cables. Bisected FerriShield Ferrites from Leader Tech are available in a wide assortment of styles and sizes and can quickly be snapped onto a cable that has already been terminated. The company offers hundreds of frequency-specific ferrite solutions for both round and flat cables. As an added advantage, Leader Tech maintains a massive inventory of Ferrishield Ferrites for immediate delivery.
